Major cities in transitional and developing countries are facing the ever-growing challenge of managing solid waste in a sustainable manner. While a variety of treatments exist for solid waste, cities are in need of a sustainable integrated municipal solid waste management (MSWM) system. Such a system is meant to assist them in selecting and investing in an appropriate combination of treatments for the waste they generate, depending on the composition and quantity of this waste. This study presents a systems analysis of the MSWM in Cairo. A constrained non-linear mathematical model is developed to represent an underlying model of a MSWM system, with six waste material flows (cardboard and paper, plastics, metals, glass, organic material, and others). The developed model depicts combinations of five treatment alternatives (composting, anaerobic digestion, mechanical biological treatment, incineration, and landfilling). The treatment methods and their capacity are determined by the model, indicating possible optimal design solutions and recommendations. Starting with an evaluation of the status quo of the MSWM system in Cairo, the paper proposes a staged strategy, involving investigating improvements to the current mixed-waste management system, then exploring the possibility of introducing at-source waste sorting. The environmental and economic implications of different scenarios are analyzed and compared. A material flow analysis, including input data uncertainties, is also conducted by applying substance flow analysis. This analysis shows the difference between the status quo and the proposed improved solutions for diverting waste from landfills and, thus, decreasing carbon dioxide emissions.

Capture Theory

According to disposal situation of municipal solid waste (MSW) in China, the method of video capture was used to identify MSW, and classify the recyclable waste and non-recyclable waste. Verifying experiments were carried on by Plastic bottles in MWS. The results showed that, proposed method can identify MSW accurately.

Many cities in China are facing a "junk siege" dilemma, municipal solid waste classified recycling is one of the effective disposal methods of garbage scientific management, and is also the best way to waste reduction, recycling and harmless, However our municipal solid waste classification recycling remain stagnant, This paper argues that it is because of many obstacles that municipal solid waste classification recycling face makes municipal solid waste classification recycling have little effect, which include public awareness needs to be improved, the limitations of traditional garbage classification, lack of corresponding laws and regulations, garbage recycling facilities not complete and the corresponding theoretical issues remain to be explored etc.

Effective Path

Rapid economic development accelerates the generation of municipal solid waste (MSW), and thereby calls for an effective and reliable waste management strategy. In the present work, we systematically investigated the status of MSW management in a mega-city of China (Guangzhou). The data were collected from literatures, government statistics and field sampling work. It can be found that a combination of waste sorting by individual residents and a necessary quantity of sanitation workers is one of the most feasible strategies to achieve a sustainable waste management. With implementation of that integrated strategy, approximately 0.03 million tons of metal, 0.24 million tons of paper, as well as 0.46 million tons of plastics can be recycled/recovered for further processing. A cost reduction of 70 million US$ is achieved in comparison with the un-optimized system due to the sale revenue of recyclable materials and the saving from waste disposal fees. The values of environmental assessment were expressed as environmental load units. The developed scenarios could decrease the environmental cost, namely, 0.66 million US$. Based on the studies, waste sorting is urgently needed in Guangzhou. However, to make the proposed strategy to be more economically feasible, the sorting should be performed individually as well as with public participation. The establishment of a win–win situation for all stakeholders is an effective path for the improvement of the integrated waste management system.

Coordination Degree

There is a general phenomenon of incoordination between garbage classification management and participation behavior, which seriously affects the sustainable management efficiency of domestic garbage. In order to solve this problem, this paper introduced the subject-object-process model into the waste classification management system, and constructed a mandatory classification management model of municipal solid waste and a comprehensive evaluation index system. Taking Beijing, China, as an example, the coupling coordination degree of garbage classification behaviors of residents in different was compared, and the coordination status of household waste management and behaviors was obtained. The results show that the synergy between government management and residents’ household waste classification behavior is between 0.40 and 0.68, and the synergy between enterprises’ participation in governance and residents’ behavior is between 0.45 and 0.75. The coordination degree between domestic waste management and residents’ participation behavior is generally in primary coordination or slight imbalance. The synergy degree between the secondary indicators of domestic waste management and residents’ behavior is higher than that of the tertiary indicators. Superposition effect of integrated management measures is better; among the psychological factors affecting residents’ classification behavior, the awareness rate and recognition degree of waste classification are very high, the awareness of environmental responsibility and social pressure are lagging behind. The study of synergy under the framework of subject-object-process not only quantifies the overall synergy between management and residents’ behavior, but also provides a method to further implement garbage classification management in a targeted manner. Based on the synergy analysis, according to the weak links of various regions, classified management is carried out around publicity and education, supervision and management, assessment, rewards and punishments.
